VReference is had to the accompanying drawings which illustrate the preferred form of the invention, though it is to be understood thatthe invention is not limited to the exact `details of construction shown and described,

as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.y

, In said drawings:

y Fig. 1 is a side elevation of one end of la carshowing the invention applied there- .to K

Fig-2 is a top plan View of the car illustrated in Fig..l; y

Fig. 3 is a sectional view of the bumper of the present invention;

Fig. 4 is a fragmentary top plan view of 'the bumper, and' y Fig.` 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 2.

This invention relates to mine cars, refern ring more particularly to a bumper construction-therefor, and 'isk a division of my prior application for mine car filed June 8, 1925, Serialy Number 35,639.`

It is one object of this invention to prol vide a mine car having a bumper which will be strong and durable in operation and which willV facilitate repairs to the car floor.

Y'Another object of the invention isto p rovide a mine car having a bumper, a portion yof which will serve as a bearing surface for an end gate attached to the car.

In the drawings, a mine car is indicated generally at A and comprises side plates 1 forming the side floorportions of the car and having theiredges bent to provide webs 2. l' Car sides 3 are provided which are carried :by the side floor portions 1 and saidy sides are preferably braces 4 extending beneath the car body from braced by means of strap y ythe top of one-side to the top of the other side and secured to the sidesby rivets 5 or the like. The car body is mounted on the usual wheels 6. i

' k ranged'longitudinally of the car with its ends projected beyond the ends of the car, and floor boards 8 form the remainder of the car floor ythis figure, it can be seen that some of the floor boards 8 project beyond the end ofthe car, 'and have 'secured thereon the bumper 9. As clearly shown in Fig.-2, the iioor boards Sadjacent the side floor portion 1 'are not engaged by the bumper. and may be moved longitudinally to remove them from vthe Icar upon removalofrthe bolts which secure them in position. After the outside lioor boards 8 have been remov'ed,the inner-` .the end braces 4 and being secured thereto by bolts 13v which extendthrough the upper and lower plates 10 and 11, floor boardsy 8 andv filler members 14, which latterare placed -betweenthe bottom plate 11 and the bottoms z of .the Vfloor boards 8. The top plate 10 rests yover and is slightly spaced yfrom the tops of the floor-boards 8a's clearly sh-ownin Fig. 5.

.As heretofore mentionechthe bumpercomprises .a `faceplate'lf. which latter is prefer- -ably` slightlyl curved from end to end, and the same is provided withA horizontal depressions 15 commencing at the ends andextending inwardly to a point adjacent the drawbar 7, as indicated at 16, the depressions forming internal recesses 17, and, of course, aninternal projection yagainst which latter lthe yiio'or boards are adapted to contact,as clearly -shownin Figs. 2 and. yItfwill be apparent from the description just above that the-depressions 15 provide, in elfect, anti-climbers for anobvious purpose. A bracket 17St is riveted to -thedrawbar 7 andthe outerend ofrthisbracket is spaced from the draw-bar vand from the bumper to provide an opening to receive theusual coupling link, the bracket beingfurther provided .with anopening-for a coupling pin 17 ,which opening is 'alined with openings 18 formed in plates 10 and 11, and with an openingfin the draw-bar 7.

Extending across the carin 4line with each .brace .4 andbeneath .the plate 10 is atie :19

which rests upon the-floor boards 8 and upon side ioor portions 1, said ties being connected to the side Yfloor portions by rivets 2O and to the'floor boards 8 by bolts 13, certain of said bolts 13 also passing through the bracket 17a, the tie plate 19, and through the top and bottom plates 10 and 11 of the bumper.4

One end of the car is provided with a swinging end gate 22 carried by arms 23 pivotally connected to the car side at 24, the gate being provided with an opening for the bracket 17 and having its lower edge seated upon'. plate 10 of the bumper, the latter providing a bearing surface for said lower edge, as will be obvious.

'Ihe drawings disclose only one end of the carried by said projecting floor portion and Y comprising a top plate, a bottom plate and a j face plate connecting said top and Ybottomy 4 Vgagement with said center ioor portion.

In witness whereof I have hereunto set my hand. c .j

car, but it is to be understood that the strucf v ture shown is duplicated at the opposite end of the car, and no particular description of said opposite end is deemed necessary. The opposite .end of the car may be provided with an end gate if desired, or with any suitable end closure well known in the art.

What is claimed is:

1. In a mine car, aibumper having a plane impact receiving center portion and inwardly depressed portions on each side there-of forming anti-climbers.

2. A bumper comprising top and bottom plates and a face platehaving a horizontally 1 extending depression yon each side of the center extending inwardly only to a point adjacent said center whereby to dene aiplanef centrally arranged impact receiving portion.

3. A bumper comprisingV horizontal parallel top and bottom plates and a face plate, the latter being provided with oppositely arranged spaced horizontal depressions extending from each side thereofv toward the center 'of said face plate.

4. A bumper of the kind described comprising a top plate, a bottomI plate and a face plate yconnecting the top and bottom plates and having a central plane surface-and recessed ends on each sideof said plane surface to define' anti-climbers for reinforcing the central plane surface. Y

5. In a mine car, a proj ectingY floor portion, a bumper supported on the projecting floor portion and provided with acorrugation on each side of the center thereof providingy i yspaced anti-climbers and a central plane impact receiving surface, said corrugations contacting with the projecting floor portions on each side of the center of the bumper. j.

6. A bumper of the kind described r4comprising a top plate, a bottom plate, anda face plate connecting the top and bottom plates c and having a planesurface arranged midway betweenthe ends thereof and a recess formed in each end of said plate and extending to the plane surface andY increasing in depth from the end to the plane surface. 7. In a mine car, a center floor portion proj ecting from the end thereofV andr a bumper Y i n i'
